*' 4 Claims. (Cl. 308-180) structions, of the usual plain bearing axlecon-- structions, such as the present A. R. A. standard plain bearingaxle. The invention consists principally in providing a bearing housingor,

carrier for the axle bearings, such carrier being provided with recessesadapted for cooperation with projections on the interior of the journalbox, such journal box projections also being adapted for use with plainaxle bearings. The invention further consists in the'railway car axleand truck construction and in the parts and 'combinations and'arrangements of parts hereinafter described and claimed.

In the accompanying drawings,

Fig. 2 is a cross-sectional view,

Fig. 3 is a vertical sectional view on the line 3-3 of Fig. 1,

Fig. 4 is a horizontal sectional view,

Fig. 5 is a perspective view of the bearing carrier,

Fig. 6 is a side view thereof,

Fig. 7 is a longitudinal sectional view thereof,A

Fig. 8 is -aviewsimilar to Fig. 3 showing a modification,

Fig. 9 is a part elevation, part sectional view of the modification.shown in Fig. 8,

Fig. 10 is Aa view similar to Fig. 9 showing the use of plain bearings;and 4Q Fig. 11 is a view similar to Fig. 8, showing plain bearings.

In the construction illustrated in Fig. 1, a truck side frame 1 has adepending elongated journal box 2 integral with each end thereof, onlyone end of the side frame being shown in the drawing.

Projecting into each journal box 2 is the reduced end portion 3 of anaxle 4 on which are mounted spaced cones or inner bearing members 5 ofantifriction bearings, such as taper roller bearings. A spacer ring 6 ismounted between the two bearing members 5 and a nut 7 is mounted on thethreaded outer end of the axle 4. At the inner end of the innermostbearing cone 5 is an oil flinger ring 8 that is mounted against ashoulder 9 -on the axle 4. The bearings lare thus rigidly held inposition.

Mounted on each inner bearing member 5 is an annular series of suitableantfriction elements, as tapered rollers 10; and a cup 11 or outerbearing member is provided for each series of antifriction elements 10.Said bearing cups 11 are mounted in the ends of a hollow bearing housingor carrier 12, beingy seated against internal annular ribs 13 in saidcarrier.

In the sides of the carrier 12, preferably above the center linethereof, are recesses 14; and at the lower part of each recess, lthecarrier is provided with an inwardly projecting ledge 15 that ispreferably crowned on`its upper surface endwise of the carrier. Thecarrier 12 is preferably provided with two sets of such openings 14 andledges 15 so as to be reversible.

The journal box 2 is provided with inwardly projecting portions 16 thatextend into said recess of said carrier. The bottom faces 17 of saidprojections are preferably flat and the end.

18 and sides 19 thereof are likewise at. A wear plate 20 may beinterposed between each ledge 15 and the cooperating journal boxprojection 16, as shown in Fig. 2.

The inner end of the journal box 2 is open and a dust closure plate 21and a dust guard holder 22 provided with a channel 23 for receiving asuitable closure member 24 are secured to the inner end of the journalbox as by screws 25.

The outer end of the journal box 2 is provided with an opening 26 in itsupper portion and with a closure cap 27 therefor, said closure cap beingsecured in position by means of a clamp spring member 28 whose lower endVis held by a loop 29 secured to said journal box. The top of thejournal box 2 is Vprovided at its outer end with a lug 30 of the kindcommonly used for hingedly securing present standard closure caps to thejournal box; so that hinged capsl of the present type may be used, ifdesired. Said lug 30 supports'the upper end of the cap shown in thedrawing.

Figs. 8 and 9 show a slightly modied construction in which the upperportion 2a only of the journal box is integral with the side frame 1.The sides of said upper portion 2a are provided along their lower edgeswith projecting flanges 31 and a separate lower journal box member 32having anges 33 around its upper edge is secured to the upper box member2a., as by U-bolts 34 extending beneath the lower member 32 and throughholes in the flanges of the two -journal box members, said bolts beingheld by means of nuts 35. Rivets or other fastening means might be used.In other particulars, the construction shown in Figs. 8 and 9 is thesame as has been described.

Figs. 10 and 11- illustrate the adaptability of the construction for usewith plain bearings, such as the present A. R. A.- standard bearings.Instead of the roller bearing axle, a standard axle 4a with a collar 41at its outer end extends into the journal box 2a. Mounted on the journalportion of the axle in the space between said projections 16 is ajournal bearing or brass 42 that is preferably provided with a linervmember 43. Said brass or journal bearing 42 is held between said collar41 and a shoulder 44 on the axle, a certain amount of looseness beingleft to permit relative motion. At the inner end of said journal bearing42 is an upstanding shoulder 45 and a wedge member 46 is mounted on saidjournal bearing. Movement of said wedge 46 in one direction is limitedby said shoulder 45 on the journal bearing and in the other direction bya lug 47 in the top of said journal box '2a. Mounted on top of saidwedge 46 and engaging the underside of the top of the journal box is afiller block or plate 48. Except for this filler block, my plain bearingmembers are the same as those constituting,

of 1oil for the bearings and oil thrown 01T by the bearings in theirrotation will be distributed to the crowned bearing ledges 15 of thecarrier, thus reducing the friction and minimizing wear of said ledges15 and the journal box projections 16. distributed to all of thebearings by reason of ,rier having recesses in its sides adapted to re-'jections, the bottom walls of said recesses on Any end thrust willlikewise be.

engagement of .the sides of said journal box projections 16 with thecarrier 1.2.

Obviously numerous changes may be made Without departing from theinvention; and I do not wish to be limited to the precise constructionshown.

What I claim is:

1. A railway car truck and journal box construction comprising a journalbox provided with internal projections at each side, an axle extendinginto said journal box, a bearing carrier surrounding said axle, saidcarrier having continuous annular .end portions and antifrictionbearings, in said annular end portions, said carceive said journal boxprojections.

2. A railway car truck and journal box construction comprising a journalbox provided with internal projections at each side, an axle extendinginto said journal box, a bearing carrier surrounding sad axle, saidcarrier having continuous annular end portions and antifriction bearingsin said annularend portions, said carrier having recesses in its sidesadapted to receive said journal box projections, said recesses being 0wider than said projections.

`3. A railway c'ar truck and journal box construction comprising ajournal box provided with internal projections at each side, an axleextending into said journal box, a bearing carrier surrounding said axleand antifriction bearings therebetween, said carrier having recesses inits sides adapted to receive said journal box prowhich said projectionsrest being crowned endwise of the carrier, the lower ends of saidprojections resting on said bottom walls of said recesses and the top ofsaid bearing carrier being clear of the journal box.

4. A railway car truck and journal box construction comprising a journalbox, an axle extending into said journal box, antifriction bear# ings onsaid axle, a carrier for said bearings, said carrier being recessed ineach side, thereby forming a horizontal`ledge in each side wall andmeans in said journal box seated on said ledges to transmit the weightof the car to said axle.
